    Article summary

    Data Input

    In order to input the required information for this pollutant into the Water Quality model, the user needs to make sure that the Tab Macrophytes appears in the WQ General Tab (please follow the description on the page Preparing a Water Quality Datafile for this). Then the user needs to select the Tab Macrophytes and type in the necessary information for this pollutant in the fields which are shown on this Tab.Alternatively the necessary information for this pollutant can be typed in the .con file opened in a Textpad editor in the datafile format mentioned below.

    Datafile format

    Line 1       MACROPHYTES

    Line 2       stmacn, stmacp, stmacs, rmacn, rmacp, rmacs

    Line 3       rmac20, q10mac, slmxmc, plea1, pexu1

    Line 4       seedmc, dethmc

    Where:

    MACROPHYTES =       keyword

    stmacn =       h alf saturation constant for nitrate uptake (mg/l)

    stmacp =       half saturation constant for phosphate uptake (mg/l)

    stmacs =       half saturation constant for silicate uptake (mg/l)

    rmacn =       nitrogen to carbon ratio

    rmacp =       phosphorus to carbon ratio

    rmacs =       silicon to carbon ratio.

    rmac20 =       Productivity rate at 20C (day)

    q10mac =       Qvalue for macrophyte growth

    slmxmc =       solar radiation required for maximum productivity (J/cm/hour)

    plea1 =       proportion of dead material that is lost by leaching of nutrients

    pexu1 =        proportion of macrophyte production that is lost by exudation of nutrients

    seedmc =       Seed concentration (g/m)

    dethmc =       mortality rate constant (M) for macrophytes (day).
